As this product is a gas, refer to the inhalation section.

Check for and remove any contact lenses. Immediately flush eyes with plenty of water
for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical
attention immediately.

In case of contact, immediately flush skin with plenty of water for at least 15 minutes
while removing contaminated clothing and shoes. Wash clothing before reuse. Clean
shoes thoroughly before reuse. Get medical attention immediately.

Call medical doctor or poison control center immediately. Move exposed person to fresh
air. If not breathing, if breathing is irregular or if respiratory arrest occurs, provide
artificial respiration or oxygen by trained personnel. Loosen tight clothing such as a
collar, tie, belt or waistband. Get medical attention immediately.

Fire-fighting media and
instructions

Apply water from a safe distance to cool container and protect surrounding area. If
involved in fire, shut off flow immediately if it can be done without risk.

Contains gas under pressure. In a fire or if heated, a pressure increase will occur and
the container may burst or explode.

Special protective
equipment for fire-fighters

Fire-fighters should wear appropriate protective equipment and self-contained breathing
apparatus (SCBA) with a full face-piece operated in positive pressure mode.

:

Immediately contact emergency personnel. Keep unnecessary personnel away. Use
suitable protective equipment (section 8). Shut off gas supply if this can be done safely.
Isolate area until gas has dispersed.

Immediately contact emergency personnel. Stop leak if without risk. Note: see section 1
for emergency contact information and section 13 for waste disposal.

Environmental precautions

Section 6. Accidental release measures

:

Avoid dispersal of spilled material and runoff and contact with soil, waterways, drains
and sewers.

Personal precautions

:

Methods for cleaning up

:

Cylinders should be stored upright, with valve protection cap in place, and firmly secured
to prevent falling or being knocked over. Cylinder temperatures should not exceed 52 °C
(125 °F).

Use only with adequate ventilation. Wash thoroughly after handling. High pressure gas.
Do not puncture or incinerate container. Use equipment rated for cylinder pressure.
Close valve after each use and when empty. Keep container closed. Avoid contact with
skin and clothing. Avoid contact with eyes. Protect cylinders from physical damage; do
not drag, roll, slide, or drop. Use a suitable hand truck for cylinder movement.

Section 7. Handling and storage

Handling

Storage

:

:

Use only with adequate ventilation. Use process enclosures, local exhaust ventilation or
other engineering controls to keep worker exposure to airborne contaminants below any
recommended or statutory limits.

Section 8. Exposure controls/personal protection

Engineering controls

Use a properly fitted, air-purifying or air-fed respirator complying with an approved
standard if a risk assessment indicates this is necessary. Respirator selection must be
based on known or anticipated exposure levels, the hazards of the product and the safe
working limits of the selected respirator.

Safety eyewear complying with an approved standard should be used when a risk
assessment indicates this is necessary to avoid exposure to liquid splashes, mists or
dusts.

Personal protective equipment for the body should be selected based on the task being
performed and the risks involved and should be approved by a specialist before handling
this product.
